NYPA Transmission Lines form the Backbone of NY’s Electricity DeliveryNYPA operates one-third of the major transmission lines in New York State, helping to form the backbone of the statewide grid for electric power distribution. Our 1,400 miles of transmission lines carry power from generation sources to substation distribution centers, where they feed the lines that connect to individual customers. From high-tech transformers and other major equipment to advanced monitoring and automated, instantaneous response capability, NYPA, coordinating with other transmission operators and the New York Independent System Operator (NYISO), is actively improving New York’s grid.
Building Capacity for Marcy South
The Marcy South Series Compensation Project, now completed, will increase power transfer capability from Upstate NY to Downstate NY and reduce transmission bottlenecks in the region.
Technology allows instantaneous control of the system, saving electricity and pinpointing problems.
"We were able to increase power flow by as much as 400 megawatts without spending a substantial amount on the construction of a new power plant, and also without having a huge environmental impact."
—Daniella Piper, project manager, Marcy South Series Compensation Project
"Re-imagining how the power gets where it’s needed means saving hundreds of millions of dollars that new transmission lines cost, not to mention surmounting years of regulatory hurdles."
—Phil Toia, NYPA vice president, transmission, writing in Electric Light & Power
